For a long time, people have argued about whether wolves and coyotes are the same species. Wolves and coyotes look nearly identical to one another, but they can be anatomically differentiated by their skulls and teeth. This is because the two species evolved independently over time — specifically in North America — with wolves evolving earlier than coyotes. Wolves' larger size allows them to hunt bigger game than coyotes, which are generally smaller than their wolf counterparts. Both species are members of the dog family, Canidae. Because wolves and coyotes are similar in appearance, it can be difficult to tell them apart. However, there are some different characteristics you can look for in order to differentiate between the two animals. Wolves have extremely long legs, extremely long back legs and a very large body mass when compared to its forelegs and head. Coyotes have short legs compared to their body mass with strong forelegs that allow them high speeds when chasing prey. Wolves tend to be slightly larger than coyotes and usually have a rough face with medium length fur and a bushier tail. Wolves and coyotes can produce offspring, but the resulting litter is unlikely to be successful. A wolf-coyote hybrid can inherit some of the physical characteristics of its wolf parent — such as long legs — while inheriting the social structure and smaller size of its coyote parent. In addition, these hybrids are often infertile. Wolves tend to weigh in at 80–120 pounds while coyotes weigh in at 20–50 pounds. When considering the height from the hind paw to the shoulder, wolves can reach 34 inches while coyotes can reach 22 inches when standing on their hind feet. Other than physical characteristics, wolves and coyotes look similar and can only be recognized by their behavior. Wolves tend to be far more aggressive and solitary while coyotes will usually travel in groups if they are foraging. Coyotes tend to travel in smaller groups consisting of only one or two individuals while wolves tend to travel in larger packs consisting of seven or eight animals. Wolves howl frequently and will defend their territory from rivals by yelping, growling or even barking. Coyotes, on the other hand, howl very rarely and howl when one member of their group is separated from the rest. http://www.cdc.gov/mmwr/preview/mmwrhtml/rr5403a2. htm http://www.pet-guide.com/petplace/dogs/genetics/wolfcoyote.html http://www.livestrong.com/article/456682-differences-between-wolves-and-coyotes/#ixzz34bWzHk7e http://animals.sandiegozoo.org/animals/coyote https://livescience.com/16674-difference-between-wolves-and-coyotes.html#page=2 http://dogtime.com/dog-health-care/wolfcoyote#ixzz34bC1DMyU https://www. cfa1e77820
